SHIN GLE CUTTING MACHINE.

Specification of Letters Patent.

Patented Apr. 7, 1914.

Application filed January 30, 1914. Serial No. 815,524.

To all whom it may concern: "Be it known that I, CHARLES NnELY, a citizen of the United States, reslding at- LEbensburg, in the county of Cambria and State of Pennsylvania, have invented certain new and useful Improvements in Shingle-Cutting Machines, of which the following is a specification, reference being had to the accompanying draw1ngs.

This invention relates to a shingle cut-- ting device and more particularly to a de vice which is designed primarily for cutting asbestos shingles.

The invention has for one of its objects to provide a cutting or trimming machine for the above purpose whereby the asbestos shingles may be easily and quickly cut without danger of breaking or inutilating the same so as to render them unfit for use.

A further object of the device is to provide a gage which may be easily and quickly set for cutting the shingles to a required size.

In its more specific aspect the invention includes a movable lever provided with a knife or cutting blade a stationary blade secured to the base uponwhich said lever is mounted, said blades being so related to each other that they do not contact in the operation of the device, and a spring con nected to said lever and normally holding the same in its raised or open position.

The invention has for a further object to produce a cutting device for asbestos shingles which may be manufactured at comparatively small cost, and is highly durable as well as etlicient and reliable in practical operation. I

With the above and other objects in view as will become apparent as the description proceeds, the invention consists in certain constructions, combinations and arrangements of the parts that I shall hereinafter fully describe and claim.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings, in which-- Figure 1 is a perspective view of a shingle cutting device illustrating the invention in its preferred form. Fig. 2 is a detail transverse section showing the arrangement of the cutting blade carried by the lever with respect to the blade on the edge of the base. Fig. 3 is a section taken on the line 33 of Fig. 1. Fig. 4 is a detail section taken on the line 44 of Fig. 1.

Referring in detail to the drawing, 5 indicates a base which is adapted to be secured upon a bench or other support by. means of the bolts 6 which extend through transversely disposed bars or cleats 7 secured'to the underside of said base. These cleats at one of their ends project beyond the adjacent longitudinal edge of the base and to the same the uprights 8 are secured. Standards 9 are fixed upon the upper surface of the base at its opposite ends, said standards being arranged in line with the uprights 8. Spacing blocks 10 are disposed between these standards and the uprights 8 and are secured to the same by means of suitable bolts or screws indicated at 11.

To the longitudinal edge of the base 5 between the standards 9 a metal plate 12 is secured, the upper edge of said plate being flush with the uppersurface of the base 5. It will be noted that one of the'posts or uprights 8 is shorter than the other and between this shorter upright and the associated standard 9 one end of a lever 13 is pivotally mounted upon the bolt 14 which connects said standard and upright. To the side of this lever which is opposed to the base 5 the metal cutting plate 15 is secured. The lower edge of this plate extends below the lower face of the lever. It is to be particularly noted from reference to Fig. 20f the drawing that the plates 12 and 15 are slightly spaced so that they will not contact with each other in the operation of the lever. The lever 13 extends between the upright and standard at the opposite end of the base 5 and is provided with a suitable handle 16. One end of the coil spring 17 is secured to the lever 13 and the other end of said spring is fixed to the spacing block 10, said spring being arranged between the upright 8 and standard 9 as clearly shown in Fig. 1.

To the upper edge of the lever 13 a plate 18 is secured. This plate is formed with diverging arms 19 having notches in their upper ends to receive a truss rod 20. The opposite ends of this rod are suitably secured to'the lever 13.

In connection with the cutting machine I employ a gage device. This gage includes a longitudinally disposed plate 21 which is mounted upon the arms 22, said arms being of channel form in cross section and provided at one of their ends with flanges 23 which are notched as at 24 to receive screws or studs 25 fixed in the edge ,of the base 5.

gage member 21. Wing nuts 29 are thread-.

ed upon the upper ends of said bolts whereby the plate 21 may be securely clamped in its adjusted position. Upon the upper sur-' face of the base 5 at one end thereof a plate 30 is secured, said plate being providedwith an upstanding flange 31 extending transversely across the-base. It will be obvious that by means of this construction, the as bestos shingles may be readil cut to any width, and for the purpose determining its width, the upper surfaces of the arms 22 on one side of the slots 26 therein may be provided -with graduations 32 with respect to which the plate 21 is adapted to be adjusted.

Having above described the construction and arrangement of the several parts of my invention, its operation may be stated as follows: The spring 17 acts by its contractile force to hold the lever 13 in an elevated position as shown in Fig. 1. The asbestos composition shingle is laid upon the base with one of its edges in contact with the upstanding flange 21 which is formed upon the inner edge of the plate 21, one end of said shingle being engaged with the flange 31 on'the plate 30. The shingle projects over the metal plate 12 which is secured to the edge of the base and beneath the lever 13. The operator forces downwardly upon the handle 16 of the lever so that the knife edge of the cutting blade 16 is brought into contact with the projecting portion of the asbestos shingle and cuts through the same. 3y spacing the cutting edge of the plate from the plate 12 so that there is no sliding contact between the same when the lever is forced downwardly, liability of the edge of the asbestos shingle being broken or mutilated so that it would be unfit for roofing purposes is obviated, and the plate 15 cuts cleanly through the shingle and leaves an WVitnesses:

manufacturing cost, and owing to its simplicity will be very strong and durable in practical use. While I have referred to the cutting device as being secured to a work bench it will-be obvious'that it may be mounted upon a stand or other support and readily moved from place to place.

While I have shown and described the preferred construction and arrangement of the several elements'employed, it will be understood that the invention is susceptible of considerable modification therein, and I therefore reserve the privilege of resorting to all such legitimate changes as may be fairly embodied within the spirit and scope of the invention as claimed.

What is claimed is:

In a cutting device of the character described, a base, uprights arranged at opposite ends of the base in spaced relation to one of its longitudinal edges, standards mounted upon the base in opposed relation to said uprights, a lever pivotally mounted atone of its ends between the standard and upright-on one end of the base, and extending between the standard and upright at the opposite end of the base, a metal plate secured to the longitudinal edge ofsaid base. a spring connected to said lever and yieldingly holding the'same in an elevated position, a cutting blade secured upon one side of said lever and in spaced relation to the plate on the base, so that said blade will not contact with said plate when the lever is lowered, a plate centrally secured upon the lever and provided with upwardly extending diverging arms, and a truss rod engaged over the ends of said arms and fixed at its ends to said lever.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses.

CHARLES NEELY.
